Definitions
- the present invention relates to a method and an apparatus for forming sheet groups from one or more sheets.
- paper handling systems are known in which, for example, two-use printed sheets are fed to a cutting machine, separated, and made available to a subsequent machine for further processing.
- the two-use printed sheets are printed using suitable machines, e.g. of a merger, placed one on top of the other and are in contact with subsequent paper handling machines for further processing.
- suitable machines e.g. of a merger
- individual sheets are also fed by a sheet feeder to subsequent paper handling machines, the sheets being provided, for example, in a stacked form in the sheet feeder.
- a collecting station being arranged in front of these machines, in which individual sheet groups are formed from one or more sheets from the sheets provided.
- the sheet groups formed in the collecting station are passed on to the subsequent machines, such as a folding unit or an inserter.
- the cycle with which individual sheets are provided by the cutting machine or the sheet feeder is higher than the cycle of the subsequent machines, that is to say the inserting machine or the folder.
- an inserter that receives sheets that are provided by a cutting machine.
- Such a cutting machine can, for example, cut 1000 times during a fixed period of time, while the inserter can only insert 100 times, for example.
- single-level collecting devices or collecting stations are known in which sheets can be fed at high speed.
- the output speed must be reduced since large stacks cannot be transported so quickly.
- a subsequent processing device e.g. a collective folder, reduces the maximum output speed. This means that the collecting station cannot collect new sheets until the previous group has left the collecting area and the stop assigned to the collecting station is closed again.
- the disadvantage of this known collecting station is that it brings about a reduction in the performance of the overall system, in particular in the case of small collecting quantities and fast forerunners, such as sheet feeders or cutting machines.
- a gap between the group that is output and the subsequent sheet must be chosen so large that with the largest collection quantity and with me.cha- existing in the company African spreading a safe function of the rake is guaranteed.
- the result of this is that paper or a sheet can only be fed from the sheet feed device (for example a cutting machine or sheet feeder) when the collecting station has issued the previous group and is again ready to receive.
- FIG. 6A shows a sheet or paper handling system 600 which has a cutting machine 602, to which a stop point or a buffer 604 is connected.
- a merger 606 is arranged downstream of the stop point 604, which in turn is followed by a stop point or a buffer 608.
- the arrows in the illustration in FIG. 6A in the individual machines indicate a sheet or paper running direction P.
- an already printed paper web is separated into individual sheets, which are then made available to the stop point 604.
- the individual sheets B are arranged side by side in the paper running direction P parallel to a machine center axis X.
- the merger 606 causes the sheets lying in the stop 604 to lie one on top of the other in such a way that they are arranged one above the other in the paper running direction P with respect to the machine center axis X.
- Merger 606 becomes the merged sheets of Transfer another stop 608, from which the sheet groups are then transferred to the collecting station 610, in which a sheet group 614 consisting of one or more sheets is formed.
- the sheet group 614 is moved out of the collecting station 610 and fed to the folding unit 612, in which the corresponding folding operation is carried out.
- the leaves are then further processed, if necessary.
- FIG. 6B shows a flow chart which shows the output times for two-sheet groups which are arranged in an odd manner, the time being plotted on the X-axis and the respective output times of the individual machines of the system on the Y-axis 600, as shown by the corresponding reference numerals on the Y axis.
- the reference number 606R indicates the output times for a sheet which is arranged to the right of the machine central axis X at the merge entrance
- 606L indicates the output time for a sheet which is located at the entrance of the merger to the left of the Machine center axis X is present.
- Cutting machine makes 24000 cuts, the length of the
- Stops are 330 mm each, and the Merger 606 outputs the individual sheets offset.
- the output times for the individual machines are 150 ms for the cutting machine 602, 120 ms for the stop point 604, 145 ms for the merger for each sheet, 70 ms for the sheet 608, and 150 ms for the collecting station 610.
- the output times of the individual components do not change, as can be seen from the lines of the same length in the diagram in FIG. 6B.
- the stopping point 604 is driven at this time, in order to provide the sheets present there at the entrance of the merger 606, which takes 120 ms.
- the cutting machine has already been put into operation beforehand in order to ensure that further sheets are fed from the cutting machine 602 after the sheets have been moved out of the stop point 604. As can be seen from Fig. 6B, this cycle is then repeated.
- the cycle time is 295ms which corresponds to approximately 12200 cycles per hour. The specified times can change due to tolerances and other mechanical variations in the components.
- FIG. 7 A further example is shown in FIG. 7, a further paper handling machine 700 “being shown in FIG. 7A which has a sheet feeder 702, a scale belt 704, a stop 706 and a collecting station 708, which extend successively along a machine central axis X in the paper running direction P.
- individual sheets B are drawn off from the sheet feeder 702 and provided to the scale belt 704, so that a plurality of sheets are arranged in a scaled manner, as can be seen in FIG. 6A.
- Individual sheets are fed from the scale belt to the stop point 706, from which they are fed to the collecting station 708 for forming a sheet group 710 from one or more sheets.
- FIG. 7B shows a flow chart which shows the output times of the shingling device 704, the stopping point 706 and the collecting station 708, the time t being plotted on the X axis and the individual components of the sheet handling system 700 on the Y axis.
- the sheet group 710 present in the collecting station 708 is started to extend, which takes 150 ms.
- the sheet group 710 present in the collecting station 708 is started to extend, which takes 150 ms.
- the extension of the sheet from the stop 706 takes 75 ms and the extension of a sheet from the device 704 to the stop 706 takes 100 ms.
- the sheet which has been moved out of the shingling device 704 is extended again after reaching the stopping point 706, this taking place at an increased speed, so that the time Is 65ms.
- the times given may change due to Change tolerances and other mechanical variations in the components.
- FIG. 8A the gross cycle rate for the system described with reference to FIG. 6 and with reference to FIG. 8B shows the gross clock power for the system described with reference to FIG. 7.
- Fig. 8A it is indicated in the column "VD group” (form group) that this is either paired, offset or mixed 1: 1.
- the forms are arranged in such a way that they are transferred side by side from the cutting machine 602 to the stop 604, that is, sheets of a group of sheets are always next to each other in pairs.
- the "staggered arrangement” means that sheets which are assigned to individual sheet groups are not arranged in pairs next to one another, but are arranged one after the other in the sheet running direction, ie while one sheet of a sheet group is already arranged in the stop point 604, the following sheet is located still in the cutting machine 602.
- FIG. 8B shows the gross cycle performance for the system described with reference to FIG. 7 for different numbers of forms depending on the envelopes or forms processed per hour.
- the forms are not grouped as in FIG. 8A, since the individual sheets are not provided lying next to one another.
- provision is made for collecting sheets provided in a buffer and, after reaching a predetermined number of sheets, ie after forming a sheet group, switching over to a second buffer level, so that the sheets contained in the first buffer level can be fed for further processing while sheets output from the cutting machine are simultaneously input into the second buffer.
- a device is described, for example, in US Pat. No. 5,083,769.
- Another solution is to store the sheets provided in a single buffer in a scaled manner, with the shingled stream continuing to form sheet groups by a predetermined distance which corresponds to the number of sheets in the sheet group to be formed, which are then output.
- Such a solution is described in DE 199 40 405 A and in DE 199 40 406 A.
- DE 4333575 AI describes a method and an apparatus for forming and moving stacks from printed sheets.
- the sheets are moved one by one and scaled one above the other so that a subsequent sheet is offset under the previous sheet.
- the stack is formed by hitting the scaly leaves against a stop.
- a gap is formed between the last sheet belonging to the stack and the subsequent sheet.
- the stop is moved away so that the stack is moved away from the sheet conveyor. The stop is then brought back into its stop position and the next stack is formed.
- the present invention seeks to provide an improved method and device for forming sheet groups, which requires the inclusion of new sheets even if the previous group has not yet completely left the collecting device or collecting station has without additional collection areas having to be provided.
- This object is achieved by a method according to claim 1, by a device according to claim 14 and by a device according to claim 19.
- the one or more sheets of a sheet group are fed into a collection area.
- the sheet stack is moved in the direction of an output unit.
- the stack of sheets is shifted vertically so that it is arranged above the collection area, so the collection area is released by lifting the finished sheet stack, so that sheets of the subsequent sheet stack in the collection area essentially coincide with the extension of the finished sheet stack can be included. Additional sheets can be fed as soon as there is a sufficient distance between the raised stack and the collecting area.
- the collecting station comprises a pivotable collecting device with at least two collecting compartments, into which one or more sheets of a sheet group are introduced.
- the collecting device is pivoted so that a further collecting compartment is assigned to the entrance of the collecting station, while at the same time the sheet group formed is moved out of the collecting station.
- the pivoting of the collecting device to the next collecting compartment ensures a sufficient distance between successive sheets for collecting in the collecting device, so that the first group of sheets is safely extended and the second group of sheets is reliably retracted against a stop.
- Another advantage of the method and the device according to the invention is that the complex "double buffer" can be dispensed with, so that the mechanical complexity, the control technology and the costs are reduced compared to such systems.

- a pair of transport rollers 118a and 118b are arranged in the sheet running direction P after the support 108.
- the transport roller 118a is arranged to be movable in the direction V and is connected via a connecting rod 120 to a drive 122 which causes the roller 118a to move in the direction V.
- the roller 118b is arranged in a stationary position.
- the collecting station 100 further comprises a stop 124, which in the exemplary embodiment shown is designed as an L-shaped angle piece, but can also be designed in the form of a stop rake.
- the stop 124 is rotatably supported by a bearing 126, a corresponding The movement of the stop 124 around the bearing 126 takes place by actuation of a drive 128 which moves a connecting rod 130 in the direction V, as a result of which the stop 124 is correspondingly tilted around the bearing 126.
- An output unit 132 is arranged behind the stop 124 in the direction of sheet travel P and comprises two output rollers 134a and 134b.
- the output roller 134a is biased against the output roller 134b by a spring 136 and is arranged to be movable in the V direction.
- the output roller 134b is connected via a connecting rod 138 to a drive 140 which, when actuated, causes the roller -134b to be displaced in the V direction and, at the same time, also causes the roller 134a to be displaced in the V direction.
- FIG. 1A shows the situation in which a sheet B enters the collecting station 100, and for the sake of further consideration it is assumed for the sake of simplicity that the sheet group to be formed consists only of the one sheet B.
- the present invention is not limited to the formation of groups of sheets consisting of only one sheet, but that the station 100 according to the invention also receives a plurality of sheets of a single group.
- the sheet B was moved in the sheet entry plane 106 onto the support 108, the movement in the sheet running direction P being ended by the stop 124.
- FIG. 1B shows the situation that arises immediately after it has been determined that a group of leaves has been completely formed.
- the actuator 128 is actuated to move the connecting rod 130 such that the stop 124 and the bearing 126 tip downward, as shown in FIG. 1B, so the path between the platen 108 and the Release output unit 132.
- the drive 122 is also actuated to move the connecting rod 122 and thus the roller 118a against the roller 118b so as to move the sheet B in the direction of the output unit 132 by driving the transport rollers 118a and 118b.
- 1B shows the situation in which the sheet B has already arrived between the discharge roller 134a and 134b.
- Fig. IC is shown what happens after the sheet B has reached the output rollers 134 of the output unit 132.
- drives 116 and 140 are actuated to move lift frame 112 and output rollers 134a, 134b into a sheet exit plane 142 that is vertically spaced from sheet entry plane 106 by a predetermined distance D.
- the drive 122 is activated in order to move the transport roller 118a vertically away from the transport roller 118b, as can be seen in FIG. IC, so as to avoid an impediment to the transport of the sheet B.
- actuator 128 is actuated so as to cause rod 124 to return stop 124 to its closed position. As shown only schematically in FIG.
- the lifting frame 112 comprises a lifting frame support 144 on which the sheet B rests when the lifting frame 112 is lifted, and the support 108 remains stationary in its original position. As soon as the situation shown in FIG. IC has been set, a new sheet B 'can be introduced into the collecting station 100.
- the collecting station according to the invention makes it possible to introduce new sheets of a sheet group, although the previous group has not yet left the collecting station.
- the collection station 100 enables the stop 124 to be opened, the upper transport roller 118a of the transport, which is in front of the stop 124, to be pressed against the lower transport roller 118b, so that the group B accelerate is inclined.
- the group B is taken over by the next transport roller 134a / 134b of the output unit, and as soon as this has happened, this transport roller, the stop 124 and at the same time the part of the group that is still in the collecting area, by Lifting device 110 is raised so far that the first sheet B 'of the next group can travel under the previous group B up to the stop 124.
- the output group is now discharged via the stop 124.
- the lifting device is lowered again past the sheets already collected, which is described in more detail below with reference to FIG. 2.
- the exemplary embodiment of the present invention described with reference to FIGS. ID to IF differs from the first exemplary embodiment in that the collecting station has a pivotable collecting device 150 which comprises at least a first collecting compartment 152 and a second collecting compartment 154.
- the first collection compartment 152 and the second compartment 154 have an entrance 152a and 154a and a common exit 156.
- the entrances 152a and 154b are located adjacent to the entrance 104, and the common exit is located adjacent to the transport rollers 118a and 118b. Because of this arrangement, both compartments 152 and 154 share the stop 124.
- the collecting compartments 152 and 154 are separated by a partition plate 158, so that the two collecting compartments 152 and 154 form in the collecting device 150.
- the collection device 150 is pivotally mounted in its entirety, wherein the Bearing (not shown) is arranged so that it is adjacent to the common exit 156, so that when the collecting device 150 moves in the direction of the arrows shown in FIG. ID, the entrances 152a, 154a of the collecting compartments 152 and 154 move towards the entrance 104 or away from the entrance 104 is made possible, at the same time the common exit 156 does not change a position adjacent to the transport rollers 118a, 118b.
- the controller 156 is effective in order to effect a corresponding movement of the collecting device 150 depending on the sheet groups to be formed and the other elements of the collecting station 100, as will be explained in more detail below.
- the sheet group here, if it is formed, remains essentially in the sheet running plane 106 when extended, so that no height shift of the output 132 is required. so that here the mechanisms for height adjustment of the output 132 shown with reference to FIGS. 1A to IC can be dispensed with.
- FIG. ID shows an initial situation in which sheets are fed to the first collecting compartment 152 via the entrance 104 and the rollers 102a and 102b. Only a sheet B is shown schematically in FIG. ID in order to maintain the clarity of the illustration. Sheet B is moved such that it moves against the stop 124 in the first collecting compartment 152. Additional sheets are placed in the bin 152 until a desired number or allowable number of sheets is received.
- the entrance 104 is provided with a so-called lock, which makes it possible for the sheets to either ascend as they arrive at the collecting station 100 and to be placed in descending order in the bins, that is, the sheets are placed either on the previous sheet or under the previous sheet.
- the controller 146 determines that the desired number of sheets of the sheet group has been formed in the collecting compartment 152, this causes the stop 124 to move downward, as shown in FIG. 1E, in which the motor 128 is actuated accordingly.
- the transport rollers 118a and 118b are moved by actuating the motor 122 so that they engage the sheet group and move them in the direction of the output 132.
- the controller 146 causes the collecting device 154 to pivot, as shown by the arrow in FIG. 1E, in order to thus input 154a of the second collecting compartment 154 in the direction of the input 104 of the collecting station 100 to move.
- the control begins with the feeding of sheets which are assigned to the second sheet group into the second collecting compartment 154.
- the collecting device By pivoting the collecting device during the extension of the first sheet group and possibly by a Accelerated extension of the first sheet group compared to the insertion of additional sheets creates a sufficiently large distance between the two sheet groups so that even if the first sheet group is not yet fully extended, additional sheets can be fed into the second collecting compartment 154 , As soon as the first group of sheets is fully extended, the stop 124 is moved back to its closed position, as shown in FIG. IF, and the sheets of the second group of sheets are received in the second collecting compartment 154.
- the movement of the collecting device 150 is carried out by a corresponding device, which is schematically designated 160 in FIG. ID, and which is, for example, similar to the motor for the lifting device of the first exemplary embodiment can be designed.
- the advantage of the present invention is that a considerable increase in performance can be achieved, and furthermore a safe function of the stop is achieved which is not subject to any influence by the group size, no mechanical controls and no wear.
- the present invention enables the collection of the next group to begin while a group is being dispensed, which can significantly increase the system's collection performance.
- the collecting station 100 is designed to collect either single sheets or two sheets lying one above the other in ascending or descending order.
- the inlet and outlet speed, i.e. H. the speeds of the transport rollers 102 and 134 as well as the stop position of the sheets are freely programmable.
- the individual drives and transport rollers are controlled by a controller 146 of the collecting station, which is shown schematically in FIG. 1.
- the controller 146 is capable of managing and buffering sheet information required for processing, such as the number of leaves in a leaf group and the like.
- the operating principle of the lifting device 110 according to the first exemplary embodiment is explained in more detail below with reference to FIG. 2. Only the lifting frame 112 is shown in FIG. 2 for the sake of simplicity.
- the lifting frame 112 comprises a first side element 202 and a second side element 204, which are arranged parallel to one another in the direction of sheet travel P (in FIG. 2, the direction perpendicular to the sheet plane), are essentially identical to one another and are height-adjustable.
- a first receiving area 206 and a second receiving area 208 are formed in the lifting member 112.
- the first and second receiving areas 206 and 208 are separated from one another by a projection 202a and 204a in the respective side elements.
- the upper receiving area 206 is delimited by the projections 202a and 204a and by covers 202b and 204b.
- FIG. 2 also shows the stationary support 108, which has already been described with reference to FIG. 1. This support is stationary, ie it does not change its position.
- FIG. 2A shows the situation which corresponds to that from FIG. 1A, namely the situation in which a sheet group B is formed.
- the sheet group B is moved toward the output unit (Figs. 1, 132), and when it is reached, the lifting frame 112 is raised to reach the position shown in Fig. 2B.
- the lifting of the lifting frame 112 moves the sheet group B on the projections 202a and 204a from the sheet entry plane into the sheet exit plane.
- a further sheet B ′ of a subsequent sheet group can be picked up in the second receiving area 208, as shown in FIG. 2B.
- the two side members 202 and 204 are moved apart with respect to the width direction of the sheet B ', so that the position shown in Fig. 2C is established.
- the lifting frame is then lowered, as shown in FIG. 2D, and the side elements are brought together again, so that the situation shown in FIG. 2A is set again.

- the cutting machine 302 is provided with a printed paper web, which is cut into individual sheets B by the cutting machine, which are introduced in the first stop 304 lying side by side to the machine center axis X.
- the sheets lying next to one another in parallel are fed to the entrance to the merger 306, which aligns the two sheets one above the other with respect to the machine central axis X, sheets at the exit of the merger being transferred to the second stop point 308 and from there to the collecting device 100 according to the invention be fed.
- the collecting device 100 outputs the sheet groups formed to the folding unit 310 for further processing.
- 1B shows a flowchart in which the time t is recorded on the X axis and the individual components of the device 300 are recorded on the Y axis.
- the diagram shows the output times of the individual components.
- a sheet group that has already been formed is started to be moved out of the collecting station 100, which takes 150 ms.
- a sheet (reference number 306L) on the left with respect to the machine center axis X at the merge entrance is moved through the merger, which takes 145 ms.
- the sheets arranged in the stop point 304 are made available to the entrance of the merger, which takes 125 ms.
- the stop point 304 is started to be provided with new, cut single sheets by the cutting machine 302, which takes 150 ms.
- the sheet which has now been introduced into the stop 308 is started to be extended there and fed to the station 100.
- the cycle time in this embodiment is 215 ms, which corresponds to approximately 16,740 cycles per hour. This represents a reduction in the cycle time by 80 ms compared to the conventional system described with reference to FIG. 6.
- FIG. 4A shows a further sheet handling system 400, which comprises a sheet feeder 402, a scale belt 404, a stop or buffer 406 and the collecting station 100 according to the invention in succession in the paper running direction.
- the sheet feeder 402 outputs individual sheets to the scale belt 404, which temporarily stores the same in a scaled manner and, at the outlet thereof, outputs individual sheets to the stop point 406, which in turn feeds sheets to the collecting device 100 according to the invention.
- 4B is a flowchart showing the output times of the individual components of the system 400 are shown, the time t being plotted on the X axis and the individual components on the Y axis.
- a sheet group that has already been formed is started to be moved out of the collecting station 100, which takes 150 ms.
- another sheet is started to be moved from the scale belt 404 into the stop point 406, which takes 115 ms.
- this sheet has reached the stop point, it is output from the stop point to the collecting station 100 at an increased speed, which takes 65 ms.
- 100 ms after the start of the extension of a sheet from the scale band a further sheet is started to be moved out of the scale band in the direction of the stop point 406, which in turn takes 115 ms.
- the use of the device according to the invention results in a cycle time of 200 ms, which represents an improvement of the cycle time by 100 ms compared to the prior art described with reference to FIG. 7.
- FIGS. 5A and 5B show the gross clock rates achievable with the present invention in tabular form for different numbers of forms in a group, and also a comparison with the systems from FIGS. 6 and 7 which use a conventional collecting station ,
- the use of the collecting station according to the invention and the application of the method according to the invention result in considerable increases in cycle performance. It is thus clear that the present invention has clear advantages over the prior art systems and apparatus in terms of the achievable cycle performance, which is achieved in that while a completed group is already leaving the collecting station, collecting further sheets for a subsequent one Group can be started.
